Recently I've a problem that the outside world couldn't access my
http/smtp/ssh... services on servers behind m0n0wall.
Here I got one of the logs which when the user at 18.104.22.168 tried to
access my http service. The server that holds the http is at
192.168.0.21. I've open port/nat/server-nat/outbound-nat all together
that were working for about half year.

This is the raw log from status.php

My ISP always blame on my m0n0wall/modem. But they're working for half
year without problem. I already open icmp and added proxy arp
(shouldn't be needed); at least for pinging/testing.
The ISP is routing my /29 subnet to the PPPoE dynamic assigned ip.
Could someone help me? I'm running out of ideas on what's going wrong.
